sadly its a motherboard issue, although it's odd that it's such a small amount of keys. See if you can remap those keys to another key that is not used
Make sure you make a backup of your registry first before changing settings using the regedit command, click on the top Computer part and then go to File > Export and save the .reg file. If anything gets messed up, import that .reg file back in by double-clicking it.
check this for remap http
